WILLIAM FUZZARD, OF NEWARK, NEW JERSEY.

Specification forming part of Letters Patent Np. 12,386, dated February13, 1855; Reissued July 10, 1855, No. 314.

To all whom t may concern:

Be it known that I, WiLLIiiM FUZZARD, of Newark, in the county of Essexand State of New Jersey, have invented a new and Improved Machine forFelting Hat-Bodies; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawing, making a part of this specification, said drawingbeing a longitudinal vertical section of my 'improved machine, the planeof section being through the center'.

The nature of my invention consists in the employment or use of a pairof corrugated rollers, placed in a swinging frame, in combination withan endless apron working overa driving drum or cylinder and between thecorrugated ro-llers. The above parts being constructed, arranged andoperating, as will be hereafter fully shown and described.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, represents a rectangular frame, having a swinging frame B, securedwit-hin it, one of the pivots on which the swinging frame works, beingshown at The swinging frame is of rectangular form, and is provided withtwo corrugated rollers, C, C', placed transversely within it. The axisof the roller, C, works in permanent bearings in the frame, B, but .theaxis of the roller, C, has its bearings in slides, D, which work ingrooves (b) in t-he inner surfaces of the side pieces of the frame B,the slides being operated by a screw, E, so that the roller, C', may beadjusted nearer to, or farther from tlie roller, C, as desired.

F, is a drum, the axis or sliaftof which runs in suitable bearings onthe upper part of the frame, A. The drum is placed transversely on theframe A, and parallel with the rollers, C, C', in the swinging frame',B. Around the drum, F, there is an endless apron G, formed of anysuitable material. This apron is of suliicient length to pass betweenthe rollers, C, C, and extend a short distance below them.

II, is a trough or basin secured to the lower part of the frame, A, andunderneath the rollers, C, C,-the length of the trough or basincorresponding with that of the Operation: The roller, S', is first moveda suitable .distance from the roller, C, by operating the screw, E, andthe hat bodies to be felted are rolled up by hand, a suitable numbertogether and placed in the fold at 4the lower part of the endless apron,G. The roller, C', is then moved near the roller C, and a rotary,reciprocating motion is given the drum, F1, by hand, or otherwise, andthe hat bodies receive a similar motion within the apron, G, underneaththe rollers,

C, C', and the requisite pressure is given the hat bodies against therollers, by depressing or bearing with the hand upon the outer end ofthe swinging frame, B.

The advantage of the above invention is that the pressure of the rollersupon the hat bodies may be graduated with the greatest nicety. This isimportant, for the hat bodies when first acted upon, or when first putin the machine, are extremely tender and liable to be ruptured. By myimproved machine, a very slight pressure may be irst given them, andprecisely similar to that of hand pressure. After the bodies aresomewhat felted and have sufficient strength the pressure may beincreased by depressing the swinging frame still more, and a continuousrotary motion given the drum, F.

The hat bodies are moistened as usual before being operated upon by the`machine, and the trough or basin, H, receives the moisture expressedfrom them, by the pressure of the rollers, C, C".

I do not claim the corrugated rollers, C, C, separately, for they havebeen previously used, although differently arranged from thosehereindescribed; but

l/Vhat I claim as new and desire to secure by Letters Iatent is,

The employment or use of the corrugated rollers, C, C, placed in aswinging frame, B, in combination with the endless apron, G, the aboveparts being constructed, arranged, and operating, in the manner and forthe purpose as herein sho-wn and described.
